Ngenxa yokusebenza kahle kwama-electrode e-graphite okuhlanganisa ukusebenza kahle okuphezulu, ukumelana okuphezulu nokushaqeka okushisayo nokugqwala kwamakhemikhali kanye nokungcola okuphansi, ama-electrode e-graphite adlala indima ebalulekile ekwenzeni insimbi ye-EAF ngesikhathi semboni yensimbi yesimanje kanye ne-metallurgy ngokufuna ukuthuthukisa ukusebenza kahle, ukunciphisa izindleko, nokukhuthaza. ukusimama.
Iyini i-Graphite Electrode?
I-GRAPHITE ELECTRODES yizinto ezingcono kakhulu zokuqhuba isithando somlilo se-arc kagesi nesithando somlilo esincibilikisayo, Akhiqizwa ngekhwalithi ephezulu yenaliti coke exutshwe, ebunjiwe, ebhakiwe futhi inqubo ye-graphitization ukuze enze umkhiqizo oqediwe.I-GRAPHITE ELECTRODES ifaneleka kahle ukusetshenziswa ezindaweni ezishisa kakhulu futhi ingamelana nokushisa okudlulele ngaphandle kokuwohloka.Okwamanje iwukuphela komkhiqizo otholakalayo onamazinga aphezulu okuguquguquka kukagesi namandla okugcina amazinga okushisa aphezulu kakhulu okukhiqizwa endaweni enzima kakhulu.
Lesi sici sinciphisa ukulahleka kwamandla futhi sithuthukisa ukusebenza kahle kwayo yonke inqubo yokuncibilikisa, okuholela ekusetshenzisweni kwamandla okuncane kanye nezindleko zokukhiqiza eziphansi.
I-Graphite Electrode Izakhiwo Eziyingqayizivele
I-GRAPHITE ELECTRODE ilungele ukusetshenziswa ezithandweni zikagesi ze-arc nakwezinye izinhlelo zokusebenza zezimboni.Izakhiwo eziyingqayizivele ziqinisekisa ukuthi i-graphite electrode ingakwazi ukumelana nezinga lokushisa eliphezulu elifinyelela ku-3,000 ° C kuya nezingcindezi ku-arc arc kagesi (EAF).
- High Thermal Conductivity- Ama-electrode e-graphite ane-conductivity enhle kakhulu yokushisa, eyenza bakwazi ukumelana nokushisa okuphezulu nezingcindezi ngesikhathi sokuncibilika.
- Ukumelana Kagesi Okuphansi- Ukumelana okuphansi kagesi kwama-electrode e-graphite kusiza ukugeleza kalula kwamandla kagesi kuma-arc arc kagesi.
- Amandla Emishini Ephakeme- Ama-electrode e-graphite aklanyelwe ukuthi abe namandla aphezulu okusebenza ukuze amelane nezinga lokushisa eliphezulu kanye namazinga okucindezela ezithandweni zikagesi ze-arc.
- I-Chemical Resistance enhle kakhulu- I-Graphite iyinto engasebenzi kakhulu ekwazi ukumelana namakhemikhali amaningi nezinto ezigqwalayo.Ama-electrode e-graphite alungele ukusetshenziswa ezindaweni zezimboni ezinokhahlo, lapho ezinye izinto zingase zehluleke ngenxa yokuhlaselwa ngamakhemikhali.
Ama-electrode e-graphite awasetshenziswa kakhulu ezithandweni zikagesi ze-arc kuphela, futhi asetshenziswa ekukhiqizeni insimbi ye-silicon, i-phosphorus ephuzi, nezinye izinsimbi ezingenayo insimbi, ama-asidi, ama-alkali, namanye amakhemikhali, izindawo ezigqwalayo.
Ama-electrode e-graphite ahlukaniswa abe amamaki amathathu ngokuya ngezinto zawo ezibonakalayo, imininingwane kanye nezinhlelo zokusebenza ezahlukahlukene ezihlobene nomthamo wesithando somlilo kagesi, umthwalo wamandla we-transformer.Amabanga asetshenziswa kakhulu ama-graphite electrode amandla aphezulu kakhulu (UHP), Amandla aphezulu (HP), namandla ajwayelekile (RP).
Ama-electrode e-UHP e-graphite ane-conductivity ephezulu eshisayo kanye nokumelana nogesi okuphansi, asetshenziselwa ngokukhethekile isithando somlilo se-arc esinamandla amakhulu aphezulu (EAF) ekuncibilikiseni insimbi ecwengiwe noma insimbi ekhethekile. I-electrode ye-graphite ye-UHP ifaneleka umthamo wesithando sikagesi esingu-500~1200kV/ A ngethani.
I-HP Graphite Electrode iyimpahla engcono kakhulu yokusingatha isithando somlilo se-arc kagesi kanye nesithando somlilo esincibilikisayo, isebenza njengesithwali sokungenisa ugesi esithandweni somlilo. I-HP graphite electrode ivamise ukusetshenziselwa isithando somlilo esinamandla kagesi se-arc(EAF) esingaba ngu-400kV/A. ngethani.
I-electrode ye-RP graphite isetshenziswa kakhulu esithandweni somlilo esivamile samandla kagesi okuyisilinganiso esingaba ngu-300kV/A ngethani noma ngaphansi.Ibanga le-RP linomthamo ophansi kakhulu we-thermal conductivity namandla emishini uma kuqhathaniswa ne-UHP graphite electrode kanye ne-HP graphite electrode.Ama-electrode angama-RP graphite afaneleka kakhulu ukukhiqizwa kwezinsimbi ezisezingeni eliphansi ezifana nokwenza insimbi, ukucwenga i-silicon, ukucwenga i-phosphorus ephuzi, ukukhiqiza izimboni zengilazi.
Ngokukhula kwesidingo semithombo yamandla ehlukile, ama-electrode e-graphite nawo adlala indima ebalulekile ekuthuthukisweni kwamaseli kaphethiloli.
Ama-electrode e-graphite anezinhlobonhlobo zezicelo ezimbonini ezahlukahlukene.Ezinye zezicelo eziyinhloko ze-graphite electrode zihlanganisa;
I-Electric Arc Furnace(EAF) ekwenziweni kwensimbi
Ukusetshenziswa kwe-graphite electrode ku-EAF steelmaking kuyisici esibalulekile sokukhiqizwa kwensimbi yesimanje.Ama-electrode e-graphite anjenge-conductor yokuletha ugesi esithandweni somlilo, okubuye kukhiqize ukushisa ukuze kuncibilike insimbi.Inqubo ye-EAF idinga amazinga okushisa aphezulu ukuze ancibilikise insimbi elahliwe, ama-electrode egraphite akwazi ukumelana namazinga okushisa aphezulu ngaphandle kokulahlekelwa ubuqotho bawo besakhiwo.Njengomhlaba iyaqhubeka nokugxila ezindleleni zokukhiqiza ezisimeme nezisebenza kahle, ama-electrode e-graphite azoqhubeka edlala indima ebalulekile ekwenzeni insimbi ye-EAF.
I-Ladle Furnace(LF)
Ama-ladle furnaces(LFs) ayizingxenye ezibalulekile zeProcess-making Process.Ama-electrode e-graphite asetshenziswa embonini yesithando somlilo we-ladle ukuze anikeze amandla kagesi aphezulu kakhulu kanye nezinga lokushisa eliphakeme kuyo yonke inqubo.Ama-electrode e-graphite aphethe izici ezinhle kakhulu ezihlanganisa ukusebenza kahle okuphezulu, ukumelana nokushaqeka okushisayo nokugqwala kwamakhemikhali, nokuphila isikhathi eside, ayisinqumo esihle sokufaka isicelo se-ladle furnace(LF). kanye nokusebenza kahle kwezindleko, kuyilapho kugcinwa amazinga aphezulu adingwa imboni.
Isithando somlilo esingaphansi kwamanzi (SEF)
Ama-electrode e-graphite asetshenziswa kakhulu esithandweni sikagesi esingaphansi kwamanzi ayingxenye ebalulekile ekukhiqizeni izinsimbi eziningi nezinto zokwakha ezifana ne-phosphorus ephuzi, i-silicon emsulwa.Ama-electrode e-graphite aphethe isici esihle kakhulu esihlanganisa ukuguquguquka kukagesi okuphezulu, ukumelana okuphezulu nokushaqeka okushisayo, kanye ne-coefficient ephansi yokwanda okushisayo.Lezi zici zenza i-graphite electrode ibe ilungele ukusetshenziswa ezithandweni zikagesi ezingaphansi kwamanzi, lapho amazinga okushisa aphakeme nezimo ezinzima kuyinto evamile.
Ama-electrode e-graphite ayizingxenye ezibalulekile enqubweni yokwenza i-Electric Arc Furnace (EAF) steelmaking.I-electrode ye-graphite isebenzisa isici esibucayi ekukhiqizeni insimbi.Indlela yokukhetha izinga elifanele kanye nosayizi we-graphite electrode, kunezici ezimbalwa okufanele zicatshangelwe nganoma yisiphi isicelo.
